Aye, they sound okay, but...
..... don't let your german demo man abuse them.... I am still wayting to hear the finall results of the Q-ranger. You'll need atleast a few hundred Q-ranger styles (that outshine everything else on the market)and the abbility to import EMC converted styles to make the Mediastation an option for most arranger musicians.
I hope you'l get Q-ranger to work flawless, (which would a miracle for a piece of software that is still in its alpha stage) with smooth chord changes. Because when i have a look at the specs of the Q-ranger its way beyound everything else available on todays market.
